3 Claims. (Cl. 20-64) This invention concerns sealing devices and consists of improvements in or relating to thresholds, windows, doors, container closures, covers, lids, and other objects to be sealed against light, air, gasses, and moisture. For the sake of brevity these will be hereinafter referred to simply as thresholds, but this term is to be understood throughout as including other objects to which they may be adapted `for the purposes stated.

Th-e invention as applied to a threshold comprises a base made in two parts; a sealing element arranged Ibetween them made of any suitable resiliant material and formed with a convex top; whereby the sealing element can be compressed to lift its top against the bottom edge of a door to insure good contact therewith by fastening a first base part in place and moving the second base part toward it, b-efore fastening the second lbase part in place, when installing the threshold under a door; and means arranged in the sides of the sealing element and the sides of the base parts contacting them, for releasable engagement with each other, to hold the sealing element in substantially normal position.

The foregoing and other features of th-e invention will be more clearly understood from the following description of three preferred examples of the invention in which:

Fig. l is an elevation in section of a first example showing the threshold base made in two parts, one of which has an extension upon which the :sealing element and the other base part rest;

Fig. 2 is'an elevation in section of the first example showing one base part moved toward the second base part, raising the convex top of the sealing element;

Fig. 3 is an elevation in section of a second example showing the sealing element and the base made in two parts; andA Fig. 4 is an elevation section of a third example showing the sealing element and the base made in two parts, each base part having an extension upon which the sealing elements rests.

Reference numeral 10, Fig. 1, 2, of the drawing designates the invention generally which has a base 11, consisting of two parts 12, 13, respectively, and the sealing element 14. The said part 12, has the portion 15, extending laterally from it defining substantially the width of said threshold and upon which said part 13, The said two base parts so arranged form a recess 16, open at the top, having opposite inner faces 17, 18, respectively, and a bottom 19. The said faces decline downwardly and outwardly from the top to form V-notch grooves with said recess bottom. The said sealing element is provided with a convex top 14a, and a central cored-out portion 20, embraced by the portions 21, 22, respectively, of said sealing element. The said portions 21, 22, have the bottom faces 23, 24, and sides 25, 26, respectively, said sides declining downwardly and outwardly from the top of thhe sealing element substantially at the same angle as said recess faces, for engagement with said V-grooves of said recess when said sealing element rests therein. The said base-part 13, is removably secured to the said base-portion 15,

to facilitate renewal of said sealing element as may be necessary or desirable from time to time.

The threshold is installed in a door opening by first securing base part 12 in place, as by nailing, 27, or by screws; next( placing the sealing element upon the extending portion 15 g and finally placing base-part 13, upon said extending portion 15, and moving same laterally against said sealing element and compressing it to hump or raise the convex top of said sealing element upwardly against the door bottom for good contact therewith. The base part 13, is then secured to said extending portion 15, Iby any appropriate means, such as screws, 28.

In Fig 3, the threshold is modified by omission of the extension portion 15, of Figs. l, 2, both base parts being made alike. The said extension is not needed in cases where the liooring is laid continuous through door openings, which permits placing the threshold parts and the sealing elements directly upon it. The numbering of the parts is similar to that of Figures l and 2. Each of the numbers shown differs from the corresponding number shown in Figures l and 2 in that it is increased by 300. The threshold is installed in a manner similar to that described above for the threshold of Figs. 1, 2.

ln Figure 4, the two threshold base parts are also made alike, but each has an extending portion, 415, 416, respectively which carry the sealing element. The threshold base parts are designated by the numerals 412, 413, and the sealing element is indicated by the numeral 414. The installation of this threshold is obvious from the foregoing description, hence will not be stated here. This concludes the description of the invention.

What is claimed is:

l. A combined threshold and sealing strip comprising in combination with a supporting iioor structure, a threshold formed in two parts each consisting of a rigid elongated member, normally disposed horizontally and having a downwardly and outwardly inclined face along one side thereof, the elongated members being adjustably and removably secured to the floor structure with their inclined faces opposed and in spaced, parallel relation to each other, and a sealing strip, formed of molded resilient material, positioned between the threshold members, the sealing strip being arched in transverse section and having a convex upper surface, a longitudinal cavity formed in its under side, and marginal portions on opposite sides of the longitudinal cavity having substantially flat bottom faces for engagement with a supporting surface, the marginal portions having out# wardly and downwardly inclined side faces for clamping engagement with the opposed faces of the threshold members whereby the sealing strip is secured to the floor structure, the arrangement being such that the effective height of the sealing strip may be varied by adjusting the spacing of the threshold members relative to each other.

2. A combined threshold and sealing strip as described in claim l in which one of the threshold members has a planar portion extending laterally outwardly therefrom, below its inclined face, for engagement with the under sides of the sealing strip and the opposite threshold member.

3. A combined threshold and sealing strip as described in claim l in which each of the threshold members has a planar portion extending laterally outwardly therefrom, below its inclined face, for engagement with the under side of the sealing strip.
